How do you know if it s essential tremor?

The diagnosis of essential tremor also requires the patient to go to the neurology department or functional neurosurgery department of a tertiary hospital under the evaluation of a specialist, and confirm whether it is essential tremor after a comprehensive assessment of physical examination, medical history, medication and instrument screening. second, whether nervousness, hunger, exertion, and tremors will worsen; Third, whether the hand tremors after drinking alcohol will be temporarily relieved and worsened the next day.

Essential tremor is a movement disorder, including congenital family hereditary and acquired essential tremor caused by various factors, its symptoms are mainly involuntary shaking of hands, head and legs, especially when nervous excitement or concentration will be aggravated, aggravation of the condition will seriously affect daily life. Essential tremor, also known as familial tremor, is a common family history disorder, according to statistics, about 60% of patients have a family history.

It is the most common movement disorder, mainly postural and motor tremor of the hands, head, and other parts of the body. Essential tremor has a conflicting clinical nature, on the one hand, it is a mild monosymptomatic disease, and on the other hand, it is a common progressive disease.

What are the symptoms now?

If you feel that you have symptoms of essential tremor, you should go to the hospital for examination in time, and if you find that you are diagnosed, you should go to the hospital in time**.

If you want to determine whether it is essential tremor, you must go to the machine in the hospital to measure it. Plus the judgment of one or three.

The diagnosis of essential tremor is generally based on the following evidence, and the typical symptoms of essential tremor appear, which are manifested as obvious and persistent tremors in the hands and forearms, mainly postural tremor and action tremor. In general, most are not accompanied by neurologic signs other than gear phenomena.

Some patients present with only head tremor but no dystonia. The disease usually lasts more than three years, there is a history of essential tremor similar to that of a family genetic member, and the tremor is lessened after alcohol consumption. In addition, it is necessary to rule out factors that cause physiologic hypertremor, drug-induced factors, a history of neurological trauma, and tremor due to psychological factors to confirm the diagnosis.

Essential tremor, also known as familial or benign essential tremor, is an autosomal dominant disorder, the most common extrapyramidal disease, and the most common tremor condition, with about 60% of patients having a family history. Postural tremor is the only clinical manifestation of the disease. Tremor is common in the hands, followed by head tremor, and tremor of the lower extremities is rare in patients.

Tremor worsens with concentration, nervousness, fatigue, hunger, and in most cases disappears temporarily after alcohol consumption and worsens the next day.

Typical symptoms are rhythmic abduction and adduction tremor of the hand, flexion and extension tremor, and pronation and supination tremor (similar to Parkinson's disease) are rare. The written word may be distorted, but it will not appear to be too small. Another commonly affected area is the craniocervical muscles, which can accumulate in the head, tongue, or vocal muscles, and manifest as severe postural tremor and head tremor in the patient's hand, including vertical "nodding" movements and horizontal "shaking the head" movements.

Tremors of the soft palate and tongue can cause dysphonia.

Typical essential tremor can be found in children, adolescents, middle-aged and elderly people, and there are two views on the peak age of onset, one is that the distribution of onset age is bimodal, that is, in the two age groups of 20 30 years and 50 60 years; Another view is that essential tremor rarely occurs in adolescents and increases with age, with an average age of onset of 37 to 47 years.

Postural tremor is common and even the only symptom in many movement disorders, including Parkinson's disease, and some patients develop postural tremor years later to Parkinson's disease, with a higher incidence of Parkinson's disease in essential tremor, which may have a special subpopulation.

The only symptom of essential tremor is tremor, which has occasionally been reported to be accompanied by anomalies in intonation and gait. Patients usually start with the upper extremities and mainly affect the upper limbs, but can also affect the head, legs, trunk, voice, and facial muscles. Presents with postural tremor and may contain both motor, intentional, or resting tremor components.

Tremor may be worse with movement toward the purpose. The frequency of tremor is 4 8Hz. The frequency at the onset of the disease is 8 12 Hz, and the frequency gradually decreases and the amplitude gradually increases with the increase of the course of the disease and age.
